Hicklin Cross Drive Transmission Dynamometers

Overview

Hicklin® Engineering has engineered and manufactured more than 30 custom cross-drive transmission dynamometers for transmission manufacturers and their customers worldwide. We incorporate various input drive and output load technologies depending upon speed and torque requirements of the test specification. Technologies used for output load absorption include eddy-current (air or water cooled), hydrostatic, hydro viscous and AC motor. Input drive motor options include AC motor and diesel or electrically driven hydrostatic input drives.

Our engineers will evaluate the transmission, the test requirements, the facility opportunities or constraints, the project goals and the budget to create a custom engineered solution to your testing challenges. Previously, we’ve developed transmission test stands to test the X-1100, HMPT-500, XTG-411, XT-1410, X-200, CD-850, CD-500, Allison HT-700, MT-600, AT-500 and Allison World Transmissions HD/MD series to name a few. Below are several examples of recent Hicklin cross drive transmission dyno projects, contact us to discuss your project.

Hicklin Cross Drive Transmission Dyno Control Room

The operator room is designed for one man operation of the entire test environment. Automated sequences programmed from the WinDyn Data Acquisition and Control system handle every aspect of the test including:

Powering the dynamometer and transmission support equipment

Filling the transmission with pre-heated and filtered transmission fluid

Ramping the input RPM and output loads to achieve manufacturer specified test requirements and notifying the operator if a parameter was not met

Operating the output drive throttles and shifting the transmission

Exporting serialized test results to a centralized database

Control room safety features

Automatic safety limits programmed for specific shut down actions

Closed circuit camera system so machine operator can see all corners of the test cell and monitor critical dynamometer and transmission components

Wireless headset system so all test cell personnel can hear and communicate at all times

Product Options

Auto Shift

The linear shift actuator controls the manual detent position of the transmission. Since it uses a cable, the Auto shift can connect to most every transmission. It can be fitted with torque measurement, up to 50 lb-ft.
